Hi, I just downloaded the latest http://hg.enzotools.org/yt/raw/stable/doc/install_script.sh and installed YT. Now, my python script (at the end of the email) quits with a "Segmentation fault" error at line-8 (yt.analysis_modules.api): [sagarwal@ember ~/junk]$ python colorbars.py parameterfile Segmentation fault If I comment out line8, then (obviously) I get the following error: Adding gaussian at -2.0 with width 0.5 and colors (0.0, 0.0, 0.502, 0.00031622776601683794) Adding gaussian at 0.5 with width 0.5 and colors (0.85737517232758309, 1.0, 0.12482388288648784, 0.005623413251903491) Adding gaussian at 3.0 with width 0.5 and colors (0.99609999999999999, 0.97250000000000003, 0.99609999999999999, 0.10000000000000001) Traceback (most recent call last): File "colorbars.py", line 36, in <module> es = EnzoSimulation(par_file, get_redshift_outputs=True, initial_redshift=50, final_redshift=0) NameError: name 'EnzoSimulation' is not defined Any ideas?

I think having to import EnzoSimulation is the old YT, the newer YT you can just do from yt.mods import * pf = load("par_file") [mine is usually something like pf = load("DD0000/DD0000")] see if that works From G.S.

Actually I just tried and you can use from yt.mods impolrt * pf = EnzoSimulation("par_file") just skip the from yt.analysis_modules.api import EnzoSimulation and it will work From G.S.

Hi Shankar, This is a worrisome error. Please leave in the import in your script and run it like this: gdb python At the gdb prompt, type "run my_script.py" where "my_script.py" is your script. When it segfaults, type: bt And then send that here, to the list. Best, Matt On Sun, Apr 24, 2011 at 12:34 AM, Agarwal, Shankar wrote:

Hi Matt, I was able to resolve the issue by replacing from yt.analysis_modules.api import EnzoSimulation par_file = sys.argv[1] es = EnzoSimulation(par_file, get_redshift_outputs=False, initial_redshift=99, final_redshift=-0.001) with import yt.analysis_modules.simulation_handler.api as es par_file = sys.argv[1] pf = es.EnzoSimulation(par_file, get_redshift_outputs=True, initial_redshift=50, final_redshift=0) In any case, your requested output is below (I think it has something to do with mpi4py, which I have not installed yet) [sagarwal@ember cqi]$ gdb python GNU gdb (GDB) SUSE (7.0-0.4.16) Copyright (C) 2009 Free Software Foundation, Inc.

Actually I just tried and you can use

from yt.mods impolrt * pf = EnzoSimulation("par_file")

just skip the from yt.analysis_modules.api import EnzoSimulation and it will work

From G.S.

...
I think having to import EnzoSimulation is the old YT, the newer YT you can just do

from yt.mods import * pf = load("par_file") [mine is usually something like pf = load("DD0000/DD0000")]

see if that works

Hi,

I just downloaded the latest http://hg.enzotools.org/yt/raw/stable/doc/install_script.sh

and installed YT. Now, my python script (at the end of the email) quits with a "Segmentation fault" error at line-8 (yt.analysis_modules.api):

[sagarwal@ember ~/junk]$ python colorbars.py parameterfile Segmentation fault

If I comment out line8, then (obviously) I get the following error:

Hi Shankar, Good to hear you resolved it. As a note, if you're running on an SGI UV machine, I've seen things like this in the past with mpi4py (which I note you say you haven't installed) if I ran in parallel and didn't use the python2.7-mpi executable. You can get this with mpi4py by running "python2.7 setup.py install_exe". -Matt On Mon, Apr 25, 2011 at 1:35 PM, Agarwal, Shankar wrote:

Hi Matt,

I was able to resolve the issue by replacing

from yt.analysis_modules.api import EnzoSimulation par_file = sys.argv[1] es = EnzoSimulation(par_file, get_redshift_outputs=False, initial_redshift=99, final_redshift=-0.001)

with

import yt.analysis_modules.simulation_handler.api as es par_file = sys.argv[1] pf = es.EnzoSimulation(par_file, get_redshift_outputs=True, initial_redshift=50, final_redshift=0)

In any case, your requested output is below (I think it has something to do with mpi4py, which I have not installed yet)

Hi Shankar,

This is a worrisome error. Please leave in the import in your script and run it like this:

gdb python

At the gdb prompt, type "run my_script.py" where "my_script.py" is your script.

When it segfaults, type:

bt

And then send that here, to the list.

Best,

Matt

Hi G.S.

Unfortunately, that did not work. If I skip "from yt.analysis_modules.api import EnzoSimulation", then i get the following error:

Actually I just tried and you can use

from yt.mods impolrt * pf = EnzoSimulation("par_file")

just skip the from yt.analysis_modules.api import EnzoSimulation and it will work

From G.S.

...
I think having to import EnzoSimulation is the old YT, the newer YT you can just do

from yt.mods import * pf = load("par_file") [mine is usually something like pf = load("DD0000/DD0000")]

see if that works

Hi,

I just downloaded the latest http://hg.enzotools.org/yt/raw/stable/doc/install_script.sh

and installed YT. Now, my python script (at the end of the email) quits with a "Segmentation fault" error at line-8 (yt.analysis_modules.api):

[sagarwal@ember ~/junk]$ python colorbars.py parameterfile Segmentation fault

If I comment out line8, then (obviously) I get the following error:
